Description：

The ISOW784x family is a series of high‑performance, quad‑channel, reinforced digital isolators with an integrated, high‑efficiency power converter. The integrated DC‑DC converter operates with high efficiency, delivering up to 650 mW of isolated power and can be configured with various input and output voltages. As a result, space‑constrained isolated designs no longer require a separate isolated power supply, thanks to these devices.
